Latin America's first gay marriage halted

Freyre and Di Bello's marriage was to coincide with World AIDS Day on Tuesday

They would attempt to get their wedding license anyway, Telam reported

Original ruling was that a ban on same-sex marriage was illegal

Court: Injunction is temporary measure to postpone marriage pending review of original ruling

Buenos Aires, Argentina (CNN) -- Latin America's first same-sex marriage, set to be held in Argentina on Tuesday, appeared derailed after a judge filed an injunction to stop the union until the issue can be reviewed further.

Judge Marta Gomez Alsina's ruling blocks an earlier holding by another judge that found city laws banning same-sex marriage unconstitutional, the court said in a statement.

Alex Freyre and Jose Maria di Bello had planned to make their marriage official at a civil ceremony and chose December 1 because it is World AIDS Day.

The registrar responsible for the civil marriages in Buenos Aires has been notified of the ruling, the court said.

The couple would attempt to get their wedding license anyway, the official Telam news agency reported.

"We're continuing with the preparations because we, as planners, nor the couple itself, have not been notified" of the injunction, said Maria Rachid, president of the Argentine Federation for Lesbians, Gays, Bisexuals and Transsexuals, according to the news agency.
